Assessment of genetic variability and correlation in hot pepper (Capsicum annum L.) germplasm
2015
Razzaq, A.
Capsicum annuum L. is the extensively cultivated species of peppers (chilies) in all over the world. For cooking purposes, its fruits are used for spiciness (capsaicin) and color (capsanthin). Genetic divergence among 25 accessions (local and exotic) collected from Ayub Agriculture Research Institute (AARI) Faisalabad, Pakistan was estimated from the data collected during the. year 2014 in Department of Plant Breeding and Genetics, University of Agriculture Faisalabad, Pakistan for different morphological and growth parameters that included fruit width, fruit length, peduncle length, number of primary branches, inter nodal length, plant height, seed index, 1000 seed weight, fresh and dry fruit weight, pericarp thickness, leaf area and seeds per fruit. Based on this characterization the plants could be grouped into 5 clusters, diversity among accessions was indicated by the wide range of D2 values whereas phenotypic correlation for all the characters was significant. Accessions with distinct identity were marked, which are likely to be quite suitable for breeding through hybridization combining desirable traits. High estimates of broad sense heritability (90%) for all the characters except peduncle length predicted that selection could be awarding in late segregating generations. Above accessions could be utilized in hybridization programme for C. annuum crop improvement.
